Balance Beads

I like Balance Beads. I don't know how they work, but a guy who works at a tire store told me they put them in truck tires regularly. I found on my speedster that they make a big difference when I drive over 35, the faster I go the smoother the ride right up to 60.
So I don't know if they would be recommended for a T that doesn't ride over 35.
The included stems are supposed to keep the beads from coming out if you let air out of the tube. The included caps indicate that the tube has balance beads in it.
The problem with installation is the constricted point at the bottom of the valve stem where it is attached to the tube. That area is not as large as the rest of the valve stem and can prevent installation.
I put the stem in a vice, just tight enough to hold it. Then I drill the stem with a 1/8" bit marked to not go deeper than 3 1/8" . That bit reams the bottom of the stem, and one has to be careful not to hit the inside of the tube. I go up, down, in , out etc. enough to make sure the passage is clear.
Then I do something that might not be recommended, but makes the beads go in easier. I use a 9/64" bit on the inside of the valve stem. I use a standard length bit and have just 1/8" held in the chuck. It wouldn't seem that 1/64 " extra would make any difference, but it cuts brass on the inside of the stem, maybe not a good idea. But, that is how I do it.
Then I carefully open the package with the balance beads, new stem, and new cap. Carefully becasue the balance beads are in a plastic bag and sometimes that bag has broken resulting in the balance beads being loose in the larger bag. You really have to be careful that these beads don't get away from you.
So I pour the beads into the bottle and put on the tubing for bead delivery, slide the tube on the end of the valve stem, and slowy pour the beads in. I have a small hammer to tap on the vice with, that helps get the beads through the stem.
Each tire took about ten minutes and I only spilled a few beads.
